  • Process for the oxidation of paraffins
    Patent number: 4038322
    Abstract: Straight-chain paraffins are nondestructively and selectively oxidized to introduce oxy and oxo functions predominantly at the 2 position by an oxidizing system comprising a compound of group II - VI metals in higher valent form and an acidic activator of dissociation constant greater than 5.10.sup.-.sup.3 or boron trifluoride, with or without molecular oxygen and with or without a solvent.
    Type: Grant
    Filed: February 6, 1976
    Date of Patent: July 26, 1977

  • Oxidation of alkylaromatics
    Patent number: 3969405
    Abstract: Process of liquid phase oxidation of the alpha carbon atom of alkylbenzenes by a manganic or cobaltic salt and an acid activator with or without an oxidation-resistant solvent either in an inert atmosphere to produce lower oxidation products of the alpha carbon atom such as alcohols or their esters; or, in the presence of molecular oxygen, to produce higher oxidation products such as aromatic aldehydes, ketones or carboxyl acids.
    Type: Grant
    Filed: April 11, 1972
    Date of Patent: July 13, 1976
    Inventors: Pierre M.J.G. de Radzitzky d'Ostrowick, Jacques D. V. Hanotier
  • Hydrocarbon conversion
    Patent number: 3937739
    Abstract: A process for the oxidation of a diethylbenzene feed which comprises passing a molecular oxygen containing gas into contact with said feed at a temperature between 100.degree. and 180.degree.C in the presence of a superbasic sulfonate of an alkaline-earth metal in an amount within the range of 0.01 to 5% by weight of the diethylbenzene feed.
    Type: Grant
    Filed: June 19, 1973
    Date of Patent: February 10, 1976
    Assignee: Labofina S. A.
    Inventors: Pierre M. J. G. de Radzitzky d'Ostrowick, Philippe J. A. Camerman
  • Selective halogenation of paraffins
    Patent number: 3935289
    Abstract: Paraffins are selectively chlorinated or brominated in position alpha to a terminal methyl group by reacting with a halogen donor in the presence of a cobaltic salt and an acid activator in an inert atmosphere.
    Type: Grant
    Filed: December 11, 1969
    Date of Patent: January 27, 1976
    Inventors: Pierre M. J. G. de Radzitzky d'Ostrowick, Jacques D. V. Hanotier, Joseph M. E. Vaerman
  • Polyvinyl chloride compositions plasticized with m-ethylphenyl phosphate
    Patent number: 3931091
    Abstract: A plasticized polyvinyl chloride composition and method for its preparation, the plasticized polyvinyl chloride composition comprising polyvinyl chloride and an organic phosphate selected from the group consisting of the phosphates of the formula (C.sub.6 H.sub.5).sub.x (m-C.sub.2 H.sub.5 C.sub.6 H.sub.4).sub.y PO.sub.4, wherein x is 0,1 or 2 and y is 1,2 or 3, x + y being 3, and mixtures of said phosphates, the amount of said organic phosphates being within the range of 20 to 100 parts by weight per 100 parts by weight of polyvinyl chloride.
